The Theory and Practice of Structural Cognitive Modifiability
According to the Teachings of Dr. Reuven Feuerstein
A Different Approach to Teaching and Learning
Feuerstein’s approach to the teaching/learning process involves a profound change in paradigm on
the part of teachers and learners. Conventional teaching may be likened to a process of pouring
information into a student’s head.
The process is described more aptly by the following diagram:
S
R
TEACHER
Figure I – 1 Conventional Teaching
As suggested by figure I-1, the teacher having something in mind to transfer to the mind of the
learner, places a stimulus (S) before the learner and then looks at the response (R). If the teacher judges
from the response that the learner has “gotten it” properly, the teacher then passes on to another stimulus.
If not, the teacher may repeat the stimulus or present another related stimulus. The teacher takes the learner
around this circuit many times and based on the responses decides if the student is “bright” or “not-sobright”. The result is that the teacher hangs an invisible sign on each student, called an “IQ”, and adjusts
the teaching pace and style accordingly. As Benjamin Bloom pointed out over 70 years ago, applying this
process to students in groups of 20 or 30 (or more) tests the speed of learning rather than the ability to
learn. Teachers will adopt the rate of teaching in such a way as to not lose interest of the fastest students
through boredom and at the same time not lose the slower students through frustration. The process then
becomes one of sorting the students rather than developing them.
The approach promoted by Dr. Reuven Feuerstein is suggested in the following diagram:
Pg II-2
Figure I-2. The Feuerstein Approach
In figure I-2, the stimulus, S, may or may not have been placed before the student by the Mediator,
represented by the letter H in the diagram. (We use the letter H to emphasize that the Mediator is a warm
human being.) The Mediator places himself or herself between the learner and the stimulus and helps the
learner to interpret the input. Some of the stimulus flows around the mediator directly to the learner. The
amount of the input intercepted depends upon the needs of the learner. The learner and mediator are
partners in the interpretation of the input. The Mediator also reflects back to the learner the response, R, so
that the learner will understand how the response appears to others. The Feuerstein approach adjusts the
process to the needs of the learner.
An essential aspect of the Feuerstein approach is a focus on the processes used by the learner. By
helping the student improve the process, it becomes possible to increase the speed of learning.
In section III we shall consider how to take into account the need to work with many students at
the same time while still paying attention to those who learn more slowly.
The mediator is guided in the mediation process by knowledge of the underlying processes in the
brain. We begin this section, therefore, with a brief review of brain structure and processes involved in
learning..
Brain Structures
The brain is made up of hundreds of billions of neurons immersed in an even larger number of
glial cells. Since neurons and glial cells are so small and their interconnections so complex, the challenge
in trying to understand the structure of the brain is very great. Until recently, it was believed that the glial
cells serve as the chemical factories for neurons and that the neurons carried out the thinking. Now it is
believed that the glial cells, in addition to serving as chemical factories, also participate in the thinking
process1.
Neurons connect to other neurons by means of little tubular extensions, called dendrites. Neurons
use dendrites to connect to one another and form structures. Some of these structures are created by
experience and are quite stable. This stability accounts for memory, for example. Other stable structures
are the result of evolution and are genetically determined. For example, at the back of the eye, nerve cells
connect to neurons, which then connect to other neurons leading to different parts of the brain. The
connections at the eye and nearby seem to be the result of evolution and are coded in our genes. Other
structures within the brain are developed through life experiences. As a child grows, it develops neuronal
structures reflecting its experiences in its environment. As Dr. Feuerstein has remarked, experience shapes
the brain and the brain shapes experience.
Recent advances in imaging allow neurologists and other scientists to peer into a living brain and
to see the differences in structure resulting from life experiences. They also learn by studying the brain
cells of animals. The brain structure in a rat which has lived with other rats in a stimulating environment
with running wheels, climbing stairs, etc., differs markedly from the structure of a rat which has lived alone
in a cage without any source of stimulation. An animal which has been subordinated to another will feel
social stress and, as shown below, develop fewer neurons.

Figure I – 2 How Social Stress Can Affect Neuron Development
When neurons connect to one another, they require energy and matter to build dendrites. This
energy is supplied by an increased flow of blood in the brain. Using positron emission tomography, Dr.
Richard Silberstein, director of the Brain Research Institute of Swinburne University in Melbourne, has
made movies of this blood flow as it occurs in different regions of the brain. The following frame from one
of his movies shows, by means of computer enhancement, the amount of blood flow activity in two
patients, working on the same problem. On the left is a “normal” person and on the right is a person
diagnosed as having attention deficit syndrome.
Figure I-3.
Brain Scan of a Normal person
Of a Person with Attention Deficit
Dr. Silbertstein’s movies show that intense blood flow occurs when a person undertakes a mental task for
the first time. From this and similar evidence, we see clearly that learning corresponds to the creation of
new brain structures.
An interesting result, easily seen using his techniques, is that if a person learns to solve a particular
problem effectively, when asked to do the problem over again, the blood flow is much less intense. Indeed,
as we know, when a problem has been solved repeatedly, we solve it without effort. We interpret these
results to indicate that once the structures have been formed, more materials and energy are no longer
required. Learning ceases. What has been learned is strengthened by repetition.
Sometimes we solve a familiar problem without even realizing we have done so. In these
circumstances, our brain seems to have a mind of its own. We drive our automobile from point to point and
have difficulty remembering the route we took. We remember a familiar tune but not the words.
We also are aware that we have some bad habits and resolve to change them. Why is it so difficult
to change what our brains do effortlessly? It takes a conscious effort to make a change in the structure of
our brain. Sometimes we find that the effort is so great it seems to be beyond our ability to make the
change, as any smoker can attest. We make a conscious effort and fail
Pg II-4
What Do We Mean by the Word Conscious?
What do we mean by conscious? I decided in 2002 to resolve this question by making a Google
search on the internet for “consciousness”. I found about 3.4 million hits. A year later I made another
search and Google returned 4.16 million hits, about a million more than I found earlier. I had concluded
that with so many papers being written about consciousness, no one really understood the subject. In my
search for the meaning of consciousness, I also read a few books. In the book Consciousness Explained by
Daniel C. Dennett2 . I read (pg 255) “With so many idiots working on the problem, no wonder
consciousness is still a mystery”.
Our brains have one important function: To make sense out of what is going on. Human brains
constantly monitor the incoming information from the five senses (sight, sound, touch, smell and taste) plus
the information generated internally (regarding the state of the body and what is stored in memory) At a
rate of about 1000 times per second, the brain decides what to do next. Some of our decision making
processes come to us genetically, via evolution. As Dennett cleverly put it (page 188) in order to persist,
all creatures must, at every instant in time, decide primarily among the four basic “F’s” (Fight, Flee, Feed
or Mate). Every brain must answer the question: “What do I do next?”
The Unique Demands of Mobility
At this point you are probably in the same state as I was when I had read Dennet’s book and
scanned the four million Google “hits”. Where is this leading? How do I find useful advice out of all this?
Then thanks to a lucky break, my daughter, Kamala Tribus, told me about a paper she had found on the
internet while looking for something else. She directed me to a paper by Dr. Bjorn Merker who takes the
view that mobile living systems have different needs for decision making than, say, plants, rooted in the
soil. Plants need to be able to react to changes in the environment. They have vascular systems which do
this, but the range of circumstances to which they require a response is limited and they make do without a
nervous system. But mobile animals have such a large variety of potential choices that they cannot
possibly rely on genetic endowment alone; they must have the capacity to learn quickly to deal with the
kinds of new situations into which their mobility thrusts them. Merker’s main point is that this mobility
creates the need to develop a “work space” in the brain for the special kinds of decision making associated
with mobility.
Dennet provides a case in point (page 177) when he cites the case of the sea squirt:
The juvenile sea squirt wanders through the sea searching for a suitable rock or
hunk of coral to cling to and make it home for life. For this task, it has a
rudimentary nervous system. When it finds its spot and takes root, it doesn’t
need its brain any more, so it eats it!
Following Dr. Merker, we may construct a list of fundamental competencies required in the brain
of an intelligent mobile creature. :

Reserving a Space in the Brain for Efficient Decision Making
According to Dr. Merker’s view, a neurological space, perhaps distributed over the brain, needs
to be selected, perhaps temporarily, where various bits and pieces of information, properly decoded, may be
the inputs and various potential decisions may be the output. For efficiency, this space excludes the preprocessing required for the various senses. I am going to call this the “Decision Space” without insisting
that it be localized or fixed in place. For the moment think of the “Decision Space” as analogous to a
subroutine in a computer program. The subroutine does not necessarily exist any particular place in
computer memory and it may be moved around during computation. It serves a function. The decision
space also seems to be analogous to the “War Room” where the information required for high level
decision making is displayed on the walls of the room while the actual processing of the field data takes
place somewhere else.
Dr. Merker argues strongly for the existence of this space for decision making because of another
characteristic of mobile animals. When I walk and move my head, at the back of my eye the image
constantly changes, yet the world about me seems to be rock steady. My eyes bob up and down as my legs
move. I glance right and left yet my image of the world remains steady. If you own a video camera, you
know that you must keep it steady while filming3. If you move your camera too much, you may induce a
sea-sickness in the audience. Obviously, as I walk, some exceptional compensatory calculations are taking
place somewhere in my brain, filtering out the effects of my movements – but I am entirely unaware of
these detailed calculations. For the brain to decide what to do next, when the basic information required for
the decision is subjected to so much pre-processing, some portion of the brain should be dedicated to
making the decision, and the pre-processing relegated to another part of the brain. This special space used
for decision making, where pre-processing has been excluded, deserves the name “consciousness.” The
other pre-processing activity may be called “subconscious activity” or “unconscious activity”.
Thus, according to Dr. Merker, consciousness derives from the evolutionary pressures created by
mobility. I prepared Figure II-4 from Dr. Merker’s figure 2.

Figure I-4 Defining a Decision Space (Adapted from Merker , by permission).
The outer circle of figure I-4 represents the brain. I do not intend that the reader attach too much
significance to the amount of area allocated to various activities, as portrayed in Figure I-4, nor do I intend
to “map” the areas in figure I-4 onto the physical brain. Dr. Merker has already done some of this
mapping. It takes an extraordinary knowledge of neurology to do so.4

In more expensive video cameras, computers pre-process the image before it goes to the tape to
remove shaking motion. The corrections are very small compared to what happens in the human visual
system.

Professor Merker cites 148 references in his paper.

The large white circle in the center represents the map of the external world required if the brain is
to make decisions regarding what to do about external events. Of course this map cannot be complete. As
Korzybski has told us, “The map is not the territory”5. However, most people tend to think that the internal
map they hold is “reality”. The brain also requires a “map” of what lies inside the skin; this part of the
brain constantly receives updated information on some of the states of internal organs. The third white
circle represents the “image of self”. Most of us do not like to know that the map of self is quite unreliable
but we have nothing better.6
The large gray area on the left of the diagram represents areas of subconscious preprocessing
activity for input information, such as the preprocessing in the optic system providing a stable view of the
world during motion of the viewer. Some of these preprocessors are the result of evolution while others are
culturally developed. Speaking, for example, involves a great deal of preprocessing before utterances. I
have decided to distinguish those pre-processing operations (which I visualize as little white “islands”)
learned from our culture differently from those pre-processings hard wired from genetics. On the right side
of the diagram, the large shaded area represents action preprocessing. We digest our food, take a breath or
a step without being conscious of how we do it. I have also indicated islands of culturally developed
enablers representing competencies which may be taught, as for example, in sports. I have located these
“islands” close to the area we associate with consciousness, to indicate they are often just outside the area
of consciousness.
I am not certain how to classify some of the unconscious effectors as resulting from evolution or
culture. We can, for example, exert some control over our breathing. While the processes which lead up to
breathing are mostly unconscious, some aspect are not. Eastern cultures differ from American culture, in
putting greater emphasis on being aware of our unconscious activities. I once witnessed a Japanese man
who could put thermometers behind his kneecaps, and while sitting motionless on a chair, cause one
thermometer to have a different temperature than the other. Experiments with bio-feedback, for example,
represent attempts to gain control over otherwise unconscious processings.
I follow Dr. Merker in depicting motivations arising from the unconscious activities, as suggested
by the arrows, and bringing the results into the image of self. More on that later.
The Most Important Part of Any System
I wish I could recall the name of the fellow who about 50 years ago asked me this rhetorical
question: ”What is the most important part of any system?” Then he answered it himself: “The part that is
not working.”
Consider, for example, what happens on a wintry day as I move from the cold outdoors into a
warm room. My glasses fog over. When I was outdoors, I looked without even being aware that I wore
glasses. I saw through them and accepted the various corrections they provided without ever a thought.
But when they fogged over, they ceased to work as before. I became conscious of the failure of that part of
the system, took off my glasses and wiped off the fog. Then I put them back on and their existence faded
from my consciousness.
Fixing Subconscious Processes When They Go Awry
Refer to figure I-4 above and consider that when something in a subconscious area is not working,
we need to move the unconscious activity into the area of consciousness. If we follow Dr. Merker in
defining consciousness as that part of the brain where decision making occurs and relegate to
unconsciousness the activities associated with pre-processing of input information for decision making,
then the question arises, how do we become aware which of the unconscious activities may not be
working? If a function stops working effectively, it becomes the most important part of the system. We

If you doubt, try answering the question “Who are you?” and compare it with the answers others give to

Pg II-7
must, therefore, bring this failing process into our conscious considerations and do something about it.
How do we know to do so?
In the example of the eyeglasses that fogged over, the answer seems obvious – but it is not. A
child with newly acquired eyeglasses will not know what to do when the child’s glasses fog over. Deming
used to say that a system cannot diagnose itself. An outside force must be brought in – a coach or a
consultant.
Let me give a different example – this time swimming. I am a fairly decent swimmer but if I am
to improve I need a coach. I think I have a good stroke and consciously work on improving it. However
the coach can see that I have not properly synchronized my stroke with my kick. The coach can observe
that the way I move my head interferes with my stroke. These are interactions I cannot see for myself; I
need a coach. If the cognitive functions supporting the decision space are not working well, we may
become aware that we do not like the outcomes of our decision process, but often we cannot identify the
cause.
Improving Intelligence.
For the purposes of this discussion I define intelligence by:
Intelligence is what you use when you do not know what to do.
We judge intelligence by observing what people do when confronted by a problem in a new
situation. Do they run around like a chicken with its head chopped off? Do they bury their head in the
sand, like the fabled ostrich? Do they wring their hands and say: “I can’t do this”? Or do they try to figure
out what the problem requires for its solution? It would be better if we were to think of intelligence as a
process. If we wish to improve intelligence, i.e. improve the process a learner uses to solve a problem, we
need a way for the learner to become conscious of what is wrong in his or her process.
The theory of what constitutes consciousness developed by Dr. Merker provides understanding of
the structure of consciousness, but taken by itself does not provide a means to improve mental processes,
i.e. intelligence. Dr. Merker’s conceptualization provides knowledge. We need to develop the know-how,
based on this new knowledge, to improve the processes we call intelligence.
Feuerstein’s Intervention Technique
Dr. Merker’s theory of consciousness provides an important conceptual basis for the improvement
of mental processes, but that theory, alone, is not enough. As the basis for the improvement process we
require an additional theory and methods to apply it. Professor Reuven Feuerstein has provided such a
theory and specific methods for applying it7. He calls his theory “The Theory of Structural Cognitive
Modifiability.” (SCM) and his method for applying it is called “Mediated Learning Experience” (MLE).
Dr. Feuerstein’s theory builds upon our understanding that what we know is represented in the brain by
structures of neurons. MLE is a method to alter or create these structures. Here are some of the
fundamental tenets of SCM
1. The brain is plastic, that is, structurally modifiable throughout life. This
premise contradicts many existing beliefs which teach that we are born with a
limited number of neurons and after early childhood, begin to lose them until in
late life we have about half as many as we started with. Fortunately, this view is
changing rapidly. The internet provides many examples of growing new neurons
in the elderly. There is hope; stupidity is not forever.

Pg II-8
2. Cultural transmission provides an important method for the creation of cognitive
structures. An adult, either a parent or a care-give, plays a crucial role in the
development of cognitive structure. A child deprived of his or her cultural
heritage will not develop cognitive structures required for survival. Intelligence
is culturally transmitted.
3. A human mediator may intervene in the mental processes of a learner, at any
age, and can cause the learner’s brain to either create a missing structure or
correct a dysfunctional cognitive structure. (Through abuse, structures may also
be destroyed.) New structural changes persist and, with use, strengthen over
time. Such changes may cause a person to begin an entirely new life trajectory.
Life is not a deterministic process; the brain influences our life experiences.
Life experiences influence the brain. Dr. Feuerstein calls the method of
intervention “Mediated Learning Experience” (MLE).
MLE provides a
method to put the theory to work.
4. The cause of the missing or dysfunctional cognitive structure is irrelevant. The
“rewiring” of the brain may be produced even in the presence of severe physical
damage to the brain, as is the case with automobile accidents, blows or even
gunshots to the head. Genetics may determine how the brain starts out but the
chromosomes do not have the last word.
5. Successful intervention involves both affect and intellect. The mediator needs to
pay attention to both the intellectual and the emotional processes. Changes in
structure always involve emotions; attempts to separate intellect and emotion
will fail. Feelings matter.
Creating Cognitive Functions Using MLE
How does our brain build these cognitive functions? Feuerstein’s theory of Mediated Learning
Experience (MLE) provides the answer. All children have experiences. The lessons they take away from
these experiences will depend on how they are mediated by a caring adult. Without assistance from an
older person, a child will not draw the lessons appropriate to the culture in which the child is raised. The
lessons learned are retained in the brain as cognitive structures.
Feuerstein’s method for correcting or creating cognitive functions relies upon two stages of
interaction with the learner. The first stage involves an evaluation device, which by means of a variety of
paper and pencil exercises, allows a trained person to identify the weak or even missing cognitive
functions. This device is called the “Learning Propensity Assessment Device” (LPAD). In the second stage
his method provides exercises, “Instrumental Enrichment”, conducted by the use of Mediated Learning
Experience, (MLE), to help the learner to strengthen or develop the needed cognitive functions.
The Feuerstein method of Instrumental Enrichment involves a series of tasks appearing to the
learner as simple puzzles. The puzzles are arranged in increasing order of difficulty so that a learner has
good chance to solve the easiest puzzles first. The puzzles are also intriguing in and of themselves.
Because the tasks are all so simple, when the learner has difficulty, a disequilibrium is established in the
brain of the learner. “I know I can do this, what is wrong?” When this disequilibrium has been established
the brain is open to suggestions.
The genius in the Feuerstein method is this: All of the tasks are ‘content free’, that is, do not
seriously depend upon prior knowledge. Thus the cognitive functions are not ‘attached’ (i.e., related) by
the brain to any specific subject. At the time the cognitive function is exercised in this ‘content free’
context, the competent mediator will ‘bridge’ to a number of specific applications in the life of the learner.
Pg II-9
In this way the mediator not only helps in creating new structures, the mediator creates linkages to other
areas of the brain.
The mediator deliberately raises the level of abstraction used by the learner. This ability to
develop an abstract representation of lessons learned gives the learner great power. It enables a person to
learn something in one context and then apply the lessons learned in another place at another time. The
process of abstracting from experience and using the abstractions in another situation is the key to the
improvement of intelligence and learning.
For example, some of the tasks given to the learner are deliberately framed so that the learner must
examine all of the instructions before starting. When the learner discovers that his or her mistakes were
caused by impulsively starting to work before understanding the problem, the mediator discusses this
lesson and asks, “Has this impulsivity ever gotten you into trouble else where in your life?”
Figure II-5. Abstracting rules and principles from experience
Dr. Deming often said that a system cannot repair itself. He was referring to management systems
and his many years of experience as a consultant taught him managers simply could not see errors in their
fundamental assumptions about how they managed. They required someone from outside, a consultant, to
bring about change. (My own experience as a management consultant also taught me, as it has taught
countless others, that how the consultant approaches the management determines the prospects for success
or failure.)
Feuerstein has likewise defined how the intervenor, called a mediator, must approach the
mediatee. From figure I-4 we may see that the decision space is surrounded by pre-processors of
information, most of which act at an unconscious level, that is, outside the smaller white areas of the
diagram. The mediator’s challenge is to bring to the area of consciousness the dysfunctional pre-processors
or, perhaps, to help the brain to develop a missing function, and to do so without energizing those other
pre-processors acting to preserve the self-image of the mediatee.
Feuerstein recognizes the role of motivation in his prescription for successful mediation. He
identifies these essential elements of mediation, which I can say from personal experience, apply equally
well to a consultant in management:
1.
Intentionality: The person (the manager or the learner) being influenced needs to understand
the purpose (intention, approach, aim) of the mediator or consultant and understand that this
purpose is consistent with his or her own objectives.
2.
Reciprocity: The mediator/consultant cannot pretend to know all the answers but rather
should treat the mediatee/client as a co-equal in the investigation of the cognitive (managerial)
processes under study.
Pg II-10
3.
Mediation of Meaning: The mediator/consultant should help the learner (manager) to
understand the implications of what is learned. Since these implications all lie in the future,
they will influence the mediatee’s (manager’s) emotional state. This influence plays a large
role in the willingness of the mediatee (manager) to allocate resources, both mental and
physical, to the pursuit of the aim.
4.
Transcendence: Whenever a specific application of the new or enhanced cognitive function
(managerial approach) has been identified as beneficial, the specific example should be
connected to other situations. This step provides a generality for the process and enhances the
potential that the cognitive function will be used more often and, therefore, made more robust
against changes in the future.
Figure I-6 illustrates the concept of transcendence. Note that the mediatee must be an active participant in
the process.

The Learning Propensity Assessment Device (LPAD)
The LPAD differs greatly from the kinds of evaluations normally used in education. Lev
Vygotsky once said, “The only legitimate reason to give an examination is for teacher and learner to decide
what to do next.” This is the spirit behind the LPAD. On the other hand, conventional educational testing
is used to grade and rank students, not improve them. Conventional testing provides an after the fact
inspection which seldom provides insights into what the learner needs to learn next.
To understand why conventional testing does not give the information required to improve the
learner’s functioning, it is necessary to analyze both the nature of a task and the cognitive functions
invoked when the task is attempted. A task may be characterized by three parameters:
1.
The content of the task the learner must know before undertaking the task.
2.
The modality in which the task is presented. Is it literal, figurative, ikonic, symbolic? Does it
depend upon graphs, charts? Does it use special jargon?
3.
The level of complexity of the problem. Complexity depends upon the degree of novelty as well
as the number of different elements comprising the task.
Pg II-11
The mental acts required to do the task may also be characterized in four parameters:
1.
The phases of the mental act. In a manner reminiscent of computer programming, we may
recognize three phases:
a) input,
b) elaboration or operation and
c) output.
2.
The cognitive operations required to perform the mental act. They may be simple, such as
identification or comparison. They may involve categorization. The operation may require
the ability to reason about spatial or temporal relations. Dr. Feuerstein has recognized over a
dozen different specific cognitive operations commonly required in problem solving.
3.
The level of abstraction. The solution of a problem may require the learner to function at a
very high level of abstraction, as for example, applying the differential calculus to the
optimization of a structure. Or the level of abstraction may be very low, as for example,
answering the question “How much is half of four?”
4.
The level of efficiency. The task may, in and of itself, impose a time or other resource
constraint. The task or its solution may require care and attention to details or accuracy. Or,
the learner may not operate efficiently and thereby create extra difficulties for himself or
herself. The low level of efficiency may be the result of fatigue, anxiety, lack of motivation
or a host of other affective reasons.
The LPAD is Dynamic not Static
The LPAD is a form of dynamic assessment as contrasted to the static assessment associated with
tests such as the IQ test. In an IQ test, the examiner provides a standardized environment, independent of
the needs of the learner. The examination materials are given to the examinee in a prescribed manner.
After the test begins, the examiner is supposed to refrain from interaction with the person being tested. It is
a sterile situation. The purpose of the examination is to rank the person being evaluated against other
persons taking the same test in another place and time. The purpose is not improvement; it is to provide a
normed reference.
In an LPAD evaluation, the evaluator interacts with the learner, giving hints where necessary. The
evaluator takes note of the kinds of help the learner requires, how the learner receives the help and what the
learner does with the help. The examiner studies the strategies the learner appears to be using and, on
occasion, asks the learner to explain what is going on. It is not at all unusual for the learner to leave the
examination with a better set of abilities than at the beginning. The purpose of the evaluation is to
determine what the learner is prepared to learn next and to discover which cognitive functions need to be
strengthened.
The LPAD has been under development for many years. As a result of observations of thousands
of learners in many different countries, Dr. Feuerstein and his staff have listed the cognitive difficulties
most likely to occur in learners. They have organized the information according to the phase of the mental
act, i.e., input, elaboration and output.

Why do Feuerstein’s Methods Work?
I believe the answer to this question lies in the way a mediator brings to a conscious level mental
processes which have been carried out at a subconscious level. By making the learner conscious of his or
her own mental processes, the learner is in a position to do something about them. How these processes are
brought to a level of awareness is the key to modifiability. The mediator has to establish a relationship with
the person being mediated which does not threaten the portion of the brain we associate with “self image”
and thereby cause it to “shut down”, and draw upon its protective mechanisms.
Pg II-13
If the transcendence process has succeeded, the structures thus created may, over time, become
one of the islands of culturally-developed pre-processing. (See Figure I-4) Note, especially, that Figure I-6
shows that the mediatee participates very actively in developing the applications in another time and place.
There are some topics which cannot be discussed seriously with people who lack direct experience
with the topic. Women tell me that no man can ever understand what it is like to give birth to a baby. You
do not know what it is like to be in a war if you have not been shot at. You cannot have a serious
discussion of sex with virgins.
Appendix I has been prepared to give the reader a small experience with MLE and one of
Feuerstein’s Instrumental Enrichment tasks. I urge the reader to work through the examples in Appendix I
with a friend and then to re-read some of the explanations of why Feuerstein’s methods are so powerful.
Putting Feuerstein’s Methods to Work
In section IV I shall address how to put Feuerstein’s methods to work in a school of engineering.
Feuerstein’s methods require individual attention. How to provide this attention in an economical and
efficient manner requires a combination of both the methods of Deming and Feuerstein.

Thinking
When we set out to learn something, it means that we try to put our mind to it. But what does it mean to
say we “put our mind to it”? Do we understand what we are doing when we “think about it”? What is
going on in our heads when we say we are “thinking”?
Consider the constellation Ursa Major, also known as the “Big Dipper”, and sometimes called the
“Plough”. Can you find it in the following photograph of the night sky?
Figure AI-1: Night sky, Northern Hemisphere.
At this moment, if you do not see the constellation, do not fret. Instead, ask yourself the questions: “How
am I searching?”, “What is my strategy?”
Suppose, for a moment, that you can see the Big Dipper. Suppose, further that you are outside, one starry
Summer night, with a friend and you point to the sky and say, “Look, there’s the big dipper.” If you friend
cannot see it, what will you do to help? How do you help him or her to “see it”? For that matter, how did
you manage to see it yourself? How do you do it?8 What is going on here? What is your brain doing when,
without much effort on your part you can impose a shape on what would otherwise be just a bewildering
array of points of light? How did your brain learn to do that?
8
I have one more question: “Is there really a big dipper up there?” Most people will say “No”. In
other words, they can see something that is not really there. The friend cannot see it and they are trying to
help him?
Pg II-15
Picking out shapes from a bewildering scene is
the most primitive form of learning. Babies
begin, very early in life, recognizing their
mother’s face and discerning shapes and sounds
in a confusing world.
When we look for our eye-glasses among the
items scattered on our desk we must begin with
a mental picture of what the eye-glasses look
like.
We have learned from our ancestors how to
‘find’ shapes in the patterns of the stars. The
shapes we recognize in the sky were not out
there we imposed them. Our ancestors showed
us a particular way of looking at the heavens
that turned out to be very useful. The big
dipper, for example, can be used to find the
North Star.
Figure AI-1 You see what?9
Like the little boy in the cartoon (left), we are
unaware that we are imposing order on what we
see. The man starts with a mental image of
what he seeks to find. In that sense he “sees”
something that is not there.
The most important question is: How do we do it? How does our brain manage to see something that is
not there? Consider the four frames in the diagram below. In the first frame (top, left) there are three
shapes, a square and two triangles:
•
Figure AI-3. A square and two triangles.
Can you construct these same three shapes using the all of the dots in the frame at top right to define the
corners of the figures? Now, consider the two frames at the bottom. Can you find the same square and two

Pg II-16
triangles, using all the dots and each one only once? (The shapes are the same size but may be overlaid and
rotated)
If you can find the square and triangles, can you explain to someone else how you did it? Do you just stare
at the cloud of dots until the images pop out? If you do, then you get the answer without consciously
thinking, without knowing how you did it! This is certainly the way you recognize the face of a loved one
in a crowd.
In this exercise we are not interested in whether you can find the three figures. The question is: “Do you
know how you do it?” Or if you cannot, do it, “Do you understand how you are trying to do it?” What
is your strategy for searching? I strongly urge the reader to discuss with a friend, the strategy for finding
a shape in the cloud of dots. Try to teach the other person your strategy for doing this task. Then, with
your friend, try the strategy using the challenges on the next page.

Some of these shapes will be found in each frame
